Sažetak
The thermodynamic point of view is used to consider bacterial chemotaxis in a capillary tube and entropy production is calculated for migrating band. It is found that the speed of the migrating band is the decreasing function of the starting concentration of the metabolizable attractant. The experimentally found dependences of speeds on the starting concentrations of galactose, glucose and oxygen are fitted with power law functions. The corresponding exponents lie within theoretically predicted interval. The acceleration of the band due to the reproduction rate of bacteria is predicted. A relationship between chemotaxis, maximum entropy production principle and formation of self organizing structure is briefly discussed.
